Detailed Description

The DtOverlayRenderer implements the overlay concept.

An overlay is a 2D scene that is drawn on top of a 3D scene. The 2D scene can contain any number of the 2D primitives which include: DtLineSegment, DtQuad, DtFilledPolygon and DtOutlinedPolygon. The DtOverlayRendered does the actual drawing of the graphical primitives.

static void makVrv::DtOverlayRenderer::fillInNormalizedProjectionMatrix ( const double  viewport[4], double  mat[16]  )

staticprotected

The projection matrix that needs to be given to to the line, quad and triangle renderers is different from the camera projection matrix when normalized coordinates are used; it incorporates the viewport information.

This will fill in that as an array of 16 doubles that the caller mus provide.

static void makVrv::DtOverlayRenderer::fillInTextProjectionMatrix ( const double  viewport[4], double  mat[16]  )

staticprotected

The projection matrix that needs to be given to the text renderer is different then the camera projection matrix.

It is the same regardless of camera type. You must pass in an array of 16 doubles.
